Abstract

The utility model discloses an automatic clutch controlled outside a shaft. A flywheel is mounted on a spline shaft, the inside of the flywheel is internally and externally processed as two different concave spaces; one concave space is shaped like an ellipse, an inner wheel is mounted in the elliptic concave space, two symmetric notches are arranged on the inner wheel, and an arc-shaped slide block with a tapered surface is placed in the notches; the other concave space is shaped like steps, an outer wheel is mounted in the step-shaped concave space, two symmetric radial holes are processed on the outer wheel, and springs and steel balls are mounted in the radial holes; a centrifugal ball supporter is mounted on the end of the spline shaft, a L-shaped lever is hinged with the centrifugal ball supporter, the outer end of the lever is connected with a centrifugal ball, the inner end of the lever is connected with a push rod with a tapered head, a spring is mounted between the lever and the centrifugal ball supporter, and after the push rod penetrates the hole of the inner wheel, the tapered head resists the slide block. Compared with various prior automatic clutches, the utility model is characterized by simple structure, easy processing, convenient use, etc.

Description

Automatic clutch controlled by outside shaft

Technical field

The application relates to a kind of auto parts machinery, a kind of specifically automatic clutch.

Background technique

Clutch is the vitals in the automotive transmission.Automobile clutch has foot-operated friction clutch and automatic clutch at present, and as fluid coupling, magnetic clutch etc., its deficiency is: foot-operated friction clutch operation inconvenience, and the automatic clutch complex structure, manufacture cost is higher, safeguards inconvenience.

Summary of the invention

The application's purpose is to overcome the existing baroque deficiency of automatic clutch, and a kind of mechanical type automatic clutch controlled by outside shaft is provided.

The structure of this automatic clutch is: by flywheel of Bearing Installation, about two kinds of different concave shaped space are processed in flywheel inside on splined shaft.The concave shaped space of the inside is processed into ellipticity, and interior wheel is installed in it, and two breach of symmetry are arranged on the interior wheel, puts into the circular-arc slide block of the band conical surface in the breach; The concave shaped space of outside is processed into step-like, and outer wheel is installed in it, is processed with two radial holes of symmetry on the outer wheel, and spring and steel ball are installed in the radial hole, has constituted the structure of free wheel device.The spline axle head also is equipped with the centrifugal globe support, be hinged with " L " shape lever on the centrifugal globe support, the outer end of lever is connected with centrifugal globe, the inner of lever is connected with the push rod of band conical surface head, between lever and the centrifugal globe support spring is housed, after push rod passed from the hole of interior wheel, the conical surface crown was on slide block.

Its working principle is: this automatic clutch rotates with engine spindle, flywheel and gearbox power input shaft join, when engine speed reaches certain speed, centrifugal globe produces centrifugal force and drives the lever pushing push rod, the conical surface crown goes out slide block and engages with the macropinacoid in flywheel ellipticity space, drives flywheel and turns round together.Cross low wheel when fast when engine speed, flywheel can still drive engine running by free wheel device, and motor and gearbox are never disconnected.Therefore free wheel device plays the function of step change.

The application's automatic clutch controlled by outside shaft is compared with existing various automatic clutches, have simple in structure, be easy to processing, characteristics such as easy to use, thereby, have good value for applications.
